ISL1557FRZ

Overview

The ISL1557FRZ is a dual operational amplifier designed for VDSL2 and ADSL line driving in DMT-based solutions. It features a high drive capability of 750mA while consuming only 6mA of supply current per amplifier. The device operates from a single 4.5V to 12V supply or ±2.25V to ±6V dual supply. It achieves a typical distortion of -80dBc at 150kHz into a 25Ω load, with bandwidth of 300MHz and slew rate of 1200V/µs. The FRZ suffix indicates operation across the full-range industrial temperature range of -40°C to +125°C. It includes control pins C0 and C1 for bias and enable/disable functions.

Feature Summary

Full-range industrial temperature specification supporting -40°C to +125°C operation
Integrated control pins for adjustable bias and output enable/disable functionality
High drive capability delivering up to 750mA from a +12V supply
Low quiescent current consumption of 6mA per amplifier

Applications

VDSL2 line drivers
ADSL2+ CPE line driving
Power line communications line drivers
HDSL2 line drivers

Procurement Notes

Verify the specific suffix FRZ confirms the extended temperature range of -40°C to +125°C against the official datasheet. Confirm package integrity for the 16-lead QFN form factor. Check RoHS compliance status as indicated in the manufacturer documentation. Ensure the component matches the intended dual op-amp application requirements before integration.

Selection Notes

Select the ISL1557FRZ when full-range industrial temperature operation is required alongside high drive capabilities. Compare the 16-lead QFN package against the 10-lead HMSOP option based on thermal and space constraints. Verify that the 300MHz bandwidth and low distortion metrics meet the specific line driver specifications for VDSL2 or ADSL applications.

Part Context

The ISL1557 belongs to the Intersil/Renesas family of high-performance analog amplifiers tailored for telecommunications line driving. The FRZ variant specifically denotes the extended temperature rating compared to the standard IRZ version. This component supports both single and dual supply configurations, providing flexibility for various DSL modem designs requiring robust signal transmission.
